NONREFILLABLE BOTTLE Filed June 7, 1934 Patented May 5, 1936 UNITED STATES PATENT OFFICE 2 Claims.

This invention relates to a non-refillable bottle which has the advantage of admitting a free flow of liquid from the bottle due to the ready admission of air. The flow of liquid and the flow 5 of air are directed into separate channels by three separate movable members in the neck of the bottle which members are partially separated when the bottle is tilted to pour out the contents.

The construction of the device is such that the valve is protected from tampering by a wire to raise the valve from the outside and to insure the closing of the valve when the bottle is righted for preventing evaporation by reason of an open valve.

Another object of the invention is to provide a device that can be easily and quickly assembled and which can be economically manufactured.

The invention is illustrated in the accompanying drawing. Figure 1 is a cross section of the device and also showing the neck of a bottle, the bottle being upright. Figure 2 is a similar view with the bottle tilted into pouring position. Figure 3 is a section on line 3-3 in Figure 1. Figure 4 is a top view of Figure 1.

The neck of the bottle is shown at I0, preferably with a shoulder l l part way down its length. The device includes a cage which fits into the neck of the bottle and consists of two sleeves. One sleeve 12 is the outer sleeve and is cemented or otherwise secured in the neck of the bottle. The outer sleeve I2 has an outwardly extending rim I3 which limits its entrance by engagement with the shoulder II. The outer sleeve I 2 also has an upwardly extending bottom flange M. The inner sleeve I5 is screwed or otherwise secured inside the outer sleeve and its bottom edge is adapted to be forced against a washer l 6 which acts as a valve seat.

The washer is preferably made of material that is slightly resilient such as rubber or fiber.

The inner sleeve has inwardly extending ribs IT on the walls of the bore which ribs extend above the top of the sleeve proper and support the baffle plate !8 which forms a top and is spaced from the sleeve proper to form the passage IS. The inner sleeve may have a flange 20 at the top, extending outwardly, and co-operating with rim l3 to clamp the washer 2| between them. 22 is a non-return valve adapted to normally engage the washer l6 which acts as a valve seat when the bottle is upright. The valve is preferably disc-shaped with a rounded bottom face to insure a more perfect fit between the valve and valve seat. 23 is a block of such a shape as to slide easily in the chamber created by the inwardly extending ribs ll. The end of the block nearest the top of the bottle has an inwardly extending recess 25. The block 23 rests on the valve 22 when the bottle is upright and the weight of the block on the valve insures a tight fit between the valve 22 and the washer 16 which acts as a valve seat. 24 is a coneshaped top piece of such size so that it may fit snugly in the inwardly extending bore 25 when the bottle is upright. The top piece has a tapered shape and fits normally into the recess of the block. On the flat surface of the top piece 24 are raised blocks which allow space for liquid and air between the baiile plate l8 and the rocking piece 24 when the bottle is tilted. The parts in the cage are not connected and are free to rock and tilt when the bottle is turned over.

After parts are assembled and placed in the filled bottle and the bottle is tilted to pour out the contents, the top piece 24 slips down along the inwardly extending ribs l1 and comes to rest against the baffle plate l8. The block 23 slides down against the top piece 24 and the 5 valve 22 opens and comes to rest against the end of the block II. The liquid can then flow out through the orifice in the washer l6 which is used as a valve seat and through the spaces between the inwardly extending ribs l1 and the baffle plate I8. The liquid flows out of the bottle as indicated by the arrows in Figure 2. The air flows in the opposite side. The return of the bottle to an upright position causes the rocking piece 24 and block 23 to assume their former position, thereby closing the valve 22.

It will be seen further on reference to Figure 1 that it is impossible to fill the bottle with the device in place in the neck of the bottle when upright. Any attempt to insert a wire or any other means through the device to open the valve is defeated because of the construction. The close fit of the valve that is obtained with the device insures of no evaporation of the contents of the bottle.

The disc-like valve 22 with the rounded bottom serves when tilted, to act as a deflector which aids in forming an air channel for air that flows in as the liquid content flows out. The channels so defined enable the liquid contents to flow freely without the shaking and vibration necessary in previous constructions. The mere trickle in some is due to the lack of a definite air passage. This has been overcome in this device and adjacent the valve and having a recess in the top end, a top piece of generally conical shape fitting loosely in the recess and having projections on its outer face for engagement with the bottom face of the baffle plate, the combined lengths of the valve, the blockrand the top piece being shorter than the distance from the baffle plate to the valve seat whereby the three enclosed pieces may each independently tilt when the bottle is tilted.

2. A non-refillable device for bottles, comprising a cage formed of two members of cylindrical form, the outer member having an inwardly turned flange at the bottom, a washer on the flange, the inner member engaging the washer to hold the washer in place, the washer forming a valve seat, the inner member having inwardly projecting longitudinal ribs in its bore and having a bafile plate supported spaced from its top, a disc-like valve with a rounded bottom face for seating on the valve seat, a block slidable and adapted to tilt slightly between the ribs, the

block having a tapered recess in its top end, and

a tapered block fitting loosely in the recess and having projections on its top face, the said three enclosed pieces being adapted to tilt independently of each other.
